AM3+ AMD 990FX DDR3 motherboard

The ASUS M5A99FX PRO R2.0 is an ATX board built around the AMD 990FX chipset for Socket AM3+ processors. It supports up to 32GB of DDR3 memory across four slots. The platform targets builders upgrading or maintaining AMD FX-era systems.

Bundled I/O shield, SATA cable and CMOS battery

The package includes a chassis I/O back panel, one SATA cable and a replacement CMOS battery so the board can be installed without sourcing those parts separately. No Wi-Fi antenna is supplied because the board has no onboard wireless module.

32GB DDR3 maximum memory capacity

The chipset and board layout limit total system memory to 32GB of DDR3. Builders planning higher capacities must choose a different platform, while those staying within this limit can populate all four slots with standard modules.
